Discussion

The project has attempted to follow he Unicode doctrine that for technical material, subscripts, superscripts, fractions and the like are to be indicated by markup. When the STIX fonts were created, the numeric sups and subs in block 2070-2095 were not included since doing so would tempt users to use them in situations where markup would be more appropriate. The only numeric (or numeric-related) superscripts included in the fonts were the three that appear in block 0 (1, 2, and 3; 00B9, 00B2 and 00B3respectively), since it was desirable that those blocks be complete.
